RAIL-FASTENER.

Specification of Letters Patent.

Patented Mar. 13, 1917.

Application led February 16, 1916. Serial No. 78,673.

To all whom t may concern.'

Be itl known that I, IGNACE B. DUnooHnn, a citizen of the United. States, residing at New Orleans, in the State of Louisiana, have invented certain new and useful 1mprovements in Rail-Fasteners, of which the following is a specification.

The invention relates to fasteners, and more particularly to the class of railway rail fasteners. l

The primary object of the invention is the provision of a rail fastener, wherein a rail can be readily and conveniently secured upon a bed plate, so that said rail will be firmly held in place, yet the same can e-X- pand and contract, without resultant loosening thereof from the bed plate, nor the displacement of said rail thereon laterally of the same.

Another object of the invention is the provision of a fastener of this character, wherein the construction thereof is novel in form to permit the quick and easy tightening of the rail on the cross tie.

A further obj ect of the invention is the provision of a fastener of this character, wherein any size rail can be securely fastened in place with despatch. n

A still further object of the invention is the provision of a fastener of this character, which is simple in construction, thoroughly reliable and efficient in its purpose, strong, durable, readily and easily adjusted, and inexpensive in manufacture and installation.

Other objects will be in part obvious and in part hereinafter fully described.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts, which will be exemplified in the construction hereinafter setvforth, and the scope of the application of which will be indicated in the claims hereunto appended.

In the accompanying drawings Figure 1, is a top plan view of a railway rail and cross tie showing the bed plate and fasteners constructed in accordance with the invention applied.

Fig. 2, is a sectional view on the line 2-2 of Fig. 1.

Fig. 3, is a sectional view on the line 3-3 of Fig. 1.

Fig. 4, is a plan view of the bed plate.

Fig. 5, is a. sectional view on the line 5-5 of Fig. 1.

Fig. 6, is a perspective view of one of the clamping blocks.

Similar referencecharacters indicate corresponding parts throughout the several views in the drawings. y

Referring to the drawings, in detail, A designates a railway rail of the ordinary well known construction, and B, the cross tie, which may be made from any suitable material, while superimposed upon Vthe top face of the latter is a bed plate 10, preferably made from metal, on which rests each rail A, of a track. The bed plate 10, is formed with slots 11, each having a medial wider portion 12, and upon this plate is arranged a casing 13, provided at its side edgeswith flanges 14, which are bent inwardly at right angles to the sides of said casing.

Arranged within each casing 13, is a slidable clamping member 15, adapted to be inserted in the slot 11 at the wider portion 12, said member being formed on opposite longitudinal sidesV thereof with grooves 16, adapted to receive the side edges of the narrower portions of the slot 11, while the end of the member 15, next to the base of the rail A, is notched at 17, to receive the base edge of the rail.

The outer end of the casing 13, is formed with a closing wall 18, in which is swiveled an adjusting screw 19, the same being threaded in a bore 20, formed longitudinally in the member 15, so that on the turning of the screw 19, the member 15, can be moved into clamping engagement with the base of the rail A, or it can be moved in the reverse direction for disengagement with the said rail.

It is, of course, understood that there are two of the fasteners mounted in the bed plate sothat they will be disposed on opposite sides of the rail A, for securelyr fastening the latter in position upon the cross tie, the bed plate being secured to the tie through the medium of suitable fasteners passed therethrough and engaged m the cross tie.

The closing wall 18, of each casing 13, is formed at its lower edge with a notched extension 22, which engages the outer end of the slot 11, to assist in holding the casing 13, in position in the bed plate.

From the foregoing it is thought that the construction and manner of use of the fastener will be clearly understood, and therefore a more extended explanation has been omitted.

lVhat is claimed is:-

l. The Combination with a slotted bed plate, of a casing removably mounted on the bed plate, a sliding clamping member m01@ able through the casing for engaging a rail, when resting upon the bed plate, and having grooves to engage the casing` and bed plate, and means connected With the easing and member for moving the latter.

2. The combination with a bed plate han ing a slot formed With a widened portion, a casing arranged on the plate and having in ternal flanges, a slidable clamping member Within the casing and insertible through the widened portion of the slot for engaging a rail when supported upon the bed plate, and haying grooves to receive the flanges and side edges of the slot, and an adjusting screw connected With the easing and acting upon the member for moving the same into clamping and unclamping positions.

ln testimony whereof l ailx my signature.
